智能文档中附件图片，返回链接后，图片后续加载不出来

找到原因了，是因为对应下载链接发生了跨域下载的问题， Access to XMLHttpRequest at 'https://www.ces-xiaoyi.com.cn/downloads/807b5d177c1a4e4cb413a9bda9d91591' from origin 'https://o.wpsgo.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

修改对应nginx配置即可
